This book was released on 2011 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to solar ultraviolet radiation (UVR) is an occupational health and safety issue for outdoor occupations, since excessive exposure is associated with negative health outcomes, including eye conditions, and skin cancers.In this study, electronic dosimeters were used to record time-stamped UVR exposure of a convenience sample of 77 workers from three occupations: building, horticulture, and roading, selected from listings in Central Otago yellow pages directories. Workers kept a diary record of concurrent sun-protective practices and completed a questionnaire on sun-related knowledge, attitudes towards suntans, and perceptions of workplace socio-cultural environment. The two outcomes were UVR exposure and sun-protective practices.Using the Haddon Matrix and Ottawa Charter for Health Promotion to structure and guide the research, variables potentially associated with the outcomes were considered from the host (worker) and the socio-cultural environment (workplace) domains. Host factors included (1) sun and skin cancer related knowledge, (2) attitudes towards suntans, and (3) perceived risk of skin cancer..

This book was released on 2004 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: A working group of 23 experts from 13 countries met in Lyon to evaluate the evidence for carcinogenicity of arsenic (mostly naturally occurring) as a contaminant of drinking-water, and of the water-disinfectant chloramine. The working group also evaluated or re-evaluated four chlorination by-products found in drinking-water, namely chloral hydrate, di- and trichloroacetic acids, and 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as MX). High-level exposure to arsenic in drinking-water occurs in some regions such as China, Latin America, Bangladesh and West Bengal. The Working Group reviewed epidemiological studies of human cancer (mainly ecological studies in Taiwan and Chile, and several case-control and cohort studies) in relation to arsenic in drinking-water. Arsenic in drinking-water (primarily inorganic, as arsenate and to a lesser extent arsenite) was evaluated as carcinogenic to humans (Group 1) on the basis of sufficient evidence for an increased risk for cancer of the urinary bladder, lung and skin. Studies on inorganic arsenic in experimental animals provided limited evidence for its carcinogenicity, but sufficient evidence was found in experimental animals for the carcinogenicity of dimethylarsinic acid (an organic form of arsenic), which produced urinary bladder tumours in rats and lung tumours in mice after oral administration.

Download or read book Solar Ultraviolet UV Radiation Exposure in Outdoor Working Environment During Cold Months written by Nanaobaayaa Owusu and published by . This book was released on 2022 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professions that are predominantly based outdoors have the risk of workers being exposed to solar ultraviolet (UV) radiation every day and during every season. Multiple studies have been conducted on outdoor workers' UV exposure during spring and summer months, but studies detailing their exposure during winter months are rare. The purpose of this study was to assess the UV exposure of groundskeepers employed at East Carolina University (ECU) during cold seasons (fall, winter, spring) compared to the summer season and to determine if UV exposure during cold seasons exceeded the Threshold Limit Values (TLVs) set by the American Conference of Governmental Industrial Hygienists (ACGIH) as occupational exposure limits. Area monitoring of UV radiation was conducted to measure the UV effective irradiance (UVeff) using a weatherproof erythema UV detector and a digital data-logging radiometer. Ambient temperature was also collected using the OSHA-NIOSH Heat Safety Tool app. Data were collected for one year in order to have data for every season. Data analysis was conducted using analysis of variance (ANOVA) to compare UVeff by month and season, and using Pearson correlation coefficient to analyze the strength and direction between UVeff and ambient temperature. Results showed that hourly and daily UV exposures exceeded the 1-hr and 8-hr TLVs, respectively, during cold months. The hourly TLV exceedance percentages for November, December, January and February were 78.0%, 62.7%, 73.4% and 74.3%, respectively. December had the lowest hourly (0.0020 ± 0.0018 mW/cm2) and daily (0.0020 ± 0.0006 mW/cm2) mean UVeff but 62.7% and 100% of the hourly and daily data still exceeded the 1-hr and 8-hr TLVs. The seasonal average UVeff for summer (0.0095 ± 0.0025 mW/cm2) was significantly higher than winter (0.0034 ± 0.0017 mW/cm2). The seasonal average UVeff for fall (0.0044 ± 0.0017 mW/cm2) compared to the summer is much lower and is closer to the winter average. The seasonal average UVeff for spring (0.0096 ± 0.0026 mW/cm2) compared to the summer is slightly higher and is also higher than the winter and fall averages. Overall, the UVeff positively correlates with the ambient temperature, as expected. Study findings demonstrate that groundskeepers and other outdoor workers, as well as the general public, should continue to use preventive measures to reduce UV exposures during the cold months to reduce risk to UV-related adverse health effects.

Slominski and published by Springer Science & Business Media. This book was released on 2012-06-02 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The skin, the body’s largest organ, is strategically located at the interface with the external environment where it detects, integrates and responds to a diverse range of stressors, including solar radiation. It has already been established that the skin is an important peripheral neuroendocrine-immune organ that is closely networked with central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides and hormones, production which is stimulated by ultraviolet radiation (UVR), biological factors (infectious and non-infectious) and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones, as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-δ steroids), secosteroids, opioids and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as the hypothalamic pituitary adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid and endocannabinoid systems. Disruptions of these axes or of communication between them may lead to skin and/or systemic diseases. These local neuroendocrine networks also serve to limit the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve endings to alert the brain to changes in the epidermal or dermal environments, or alternatively to activate other coordinating centers by direct (spinal cord) neurotransmission without brain involvement. Furthermore, rapid and reciprocal communications between epidermal and dermal and adnexal compartments are also mediated by neurotransmission including antidromic modes of conduction. Lastly, skin cells and the skin as an organ coordinate and/or regulate not only peripheral but also global homeostasis.
